This is the Fuji camera that Bill and I modified. There seems to be many variations sold in the same package. But until your board they seem to all be functionally equivalent. I think this is Bill's photo also.

Hi xee,

Thank you for your reply and efforts.

I drew a circle around the whole area that is where the switch was. This is a switch that had 2 long thin copper extensions on it going up to where the little camera switch was, if I remember.

Yes, this is a new fuji camera with a continuous flash. the expiration date on the box says 2009/09. Maybe they are older stock... or maybe newer.

Here is the pic.

thanks

Hi all,

This thread is great. Thanks to Pirate for starting it and all the other making it a great read.

I showed the circuit to my son in law and he told me that it is very close to the electronic fly swatter circuit.
Mine is using 2 AA batteries and can fry any critter that gets slapped. It was also cheap at $5.

Take care,

Michel

On my boards the black rectangular switch with a hole and two long prongs was the shutter switch, not the flash charge switch. It took me quite a while to figure out how to modify the circuit board I have. Without the ability to test the traces to see where they go I do not think I can be of much help to you. I would suggest buying another board. My experience is that what you get in the package is pure chance. If you buy another maybe it will be like the two boards I have and the board Bill has. The cameras in the package seem to all be rebuilt used units. What you get seems to depend on what was available to be rebuilt.

i have seen thease .....   lol   looks like ss wire as the swatter   

those in canada home hardware sold thease units....

can we tie it all togather.... now?!?!?!?!


take your cam flash curcuit ...  the out put ....  put it to a coil 50 turns {lets call this a control }wound on another coper wire
{lets call this a collector }         aka..... OTTOS TEST 

PASS ENGERY THROUGH THE WIRE ...  {collector}   impose the kicks {from the control } in that engery flowing throught the wire
{the collector} 

what is the result?

ps throw some soft iron in it to keep it from flying all over the place  perhaps ferroite    the jt operates similar to this ......

ist!
